335 POWDER USERS

[4barrel]

This may have been talked about before. I bought a 308 rifle in the 70s & a lyman reload manual. The owner of the pawn shop suggested 335 powder. After I blew out 3 extractors I sold it. Years later I bought another Lyman manual. I think this data was the problem. All 335 powder for jacketed .308 was a lot more grains in the #46. The #48 manual is a lot less powder. IF YOU HAVE A # 46 LYMAN YOU MAY WISH TO CHANGE THE DATA ON 335 for 308 only. I looked on the Hodgdon data & they have 42- start & 46.5 high for currant loads on the 125 bullet. 5 grains is a lot of difference. Both of these are Lyman books. Photos 1-2 are #46. 3-4 are #48.

Always use as many sources of data as possible to verify that your load is safe. If one source is significantly higher or lower that the rest, you ignore it. I don't consider the various Internet forums to be reliable sources. The data provided by the manufacturers or distributors on the Internet is as reliable as the hard cover books they produce.

If in doubt I always consult my old Lyman #45 1970 manual first then the powder manufacturers flyer and last Lee's manual. I mostly use whatever Lyman lists as their accuracy load and surprisingly it is 99% of the time the most accurate.Most of my loading for Rifles tends to stay on the midrange to mild side so I really don't have to worry too much about excess pressure and for my hunting and paper punching they do everything I need them to do.

Pistol and Revolver loads I tend to like warm but not usually maxed out so I am much more careful about where my data comes from and always recheck for pressure signs when I go to a new batch of powder.
